Remote or computer controlled aircrafts were developed for military uses but are now carrying instruments that contribute to our understanding of cloud-climate interaction - a critical issue in global climate change research. In this talk, Dr. David Sowle discusses the benefits of converting technology from military to civilian use and explains the particulars of using unpiloted aircraft to help understand climate change better. This talk was taken from a meeting entitled, "Radiation Feedbacks and the Credibility of Atmospheric Models," and is part of the Walter Orr Roberts Public Lecture Series. This is presentation of the Aspen Global Change Institute. Recorded on July 13, 1994 in Aspen, Colorado. Visit AGCI online at www.agci.org.
